Three Palestinian boys were killed in an Israeli air strike near the Gaza Strip border fence on Sunday, medical officials in the Hamas-run enclave said. The Gaza Health Ministry said two of the dead were aged 13 and one aged 14. Gaza medics have tallied more than 216 Palestinians killed by Israeli forces at the border during almost seven months of Palestinian protests against Israel's blockade of the territory and in support of the right of Palestinian refugees to return to lands in Israel. More than 17,000 Palestinians have been wounded, many of them by Israeli gunfire. One Israeli soldier has been killed by a sniper. Israel says its lethal response is necessary to prevent armed infiltrations from Gaza. The violence has occasionally escalated into shelling exchanges that Israel has warned could trigger a war, while Egypt and the United Nations have repeatedly mediated truces. <strong>_____________</strong> <strong>Read more:</strong> <strong><a href="https://www.thenational.ae/world/mena/palestinian-dies-of-wounds-after-gaza-clashes-1.785036">Palestinian dies of wounds after Gaza clashes</a></strong> <strong><a href="https://www.thenational.ae/world/mena/israeli-minister-of-intelligence-to-make-official-visit-to-oman-1.785190">Israeli minister of intelligence to make </a></strong><a href="https://www.thenational.ae/world/mena/israeli-minister-of-intelligence-to-make-official-visit-to-oman-1.785190"><strong>official</strong></a><strong><a href="https://www.thenational.ae/world/mena/israeli-minister-of-intelligence-to-make-official-visit-to-oman-1.785190"> visit to Oman</a></strong> <strong><a href="https://www.thenational.ae/world/mena/palestinian-militants-agree-truce-after-exchange-of-fire-with-israel-1.784898">Palestinian militants </a></strong><a href="https://www.thenational.ae/world/mena/palestinian-militants-agree-truce-after-exchange-of-fire-with-israel-1.784898"><strong>agree</strong><strong> truce after </strong><strong>exchange</strong></a><strong><a href="https://www.thenational.ae/world/mena/palestinian-militants-agree-truce-after-exchange-of-fire-with-israel-1.784898"> of fire with Israel</a></strong> <strong>_____________</strong> In Sunday's incident, Isreali military said an aircraft struck "three terrorists adjacent to the fence who were trying to sabotage it and were apparently planting a bomb". Four Palestinians were killed at the border on Friday. A Gaza militant group responded by firing a volley of missiles into Israel, prompting scores of Israeli retaliatory air strikes on Saturday but nobody was killed. Two million Palestinians live in Gaza, most of them stateless descendants of people who fled or were driven from homes in Israel at its founding in 1948. The narrow seaside territory has been ruled by Hamas, an Islamist group, since 2007, during which time it has fought three wars against Israel. Israel and Egypt have maintained a blockade for security reasons, which the World Bank says has brought the territory to economic collapse that has left it almost entirely dependent on international aid and without adequate electricity, health care or clean water.
